[10] The observation of Sunday was brought in by the Jesuits, who found it easier to induce them to observe both days than to consent to a substitution of the first for the seventh day. [11] The Abyssinians still retain the physiognomy and olive complexion of the Arabs, and afford an incontestable evidence that three thousand years can neither change the colour nor the intellectual capabilities of the human species. Under the burning sun of Africa, the Abyssinian, a branch of the great Caucasian family, has preserved the name and semblance of Christianity and civilization through the wreck and revolutions of ages, and amid the tempests of foreign and domestic dominations. Conscious of his ignorance, he once sought the fraternity of Europe for the sake of her letters and her arts. But how is it with the Nubian, whose unequivocal African descent is betrayed by his stupid features, black colour, and woolly hair, yet who enjoyed equal or superior advantages in ancient times? The history of his race would attest to the truth in this case. He has relapsed into that barbarism which seems to be his native element, and from which he appears incapable of preserving himself. The only memorials of his Christianity are a few words, of which he is incapable of understanding the sense; the only traces of his civilization a few heaps of sculptured ruins. [12] The negotiations of Justinian with the Abyssinians are mentioned by Procopius, John Malala, and others. The original narrative of the ambassador Nonnosus is quoted by the Historian of Antioch, and Photius has given a curious extract. Justinian reigned over the Greek empire from 527 to 565. [13] The present village of Anuma is conspicuous by the ruins of a splendid Christian temple, and seventeen obelisks, of Grecian architecture. According to Alvarez, it was in a flourishing state in 1520, but was ruined the same year by the Turkish invasion. [14] Those who desire to form an acquaintance with Abyssinian history may consult Procopius, Baronius, Cosmos, Indicopleustus, Alvarez, Lobo, and Bruce. In these works, the subject is very amply and ably treated. CHAPTER II. SEVENTH-DAY BAPTISTS IN EUROPE. SECTION I. WALDENSES, ALBIGENSES, PASAGINIANS, ETC.—THEIR SABBATICAL CHARACTER EXAMINED. It is not my design to give even an abridged account of ecclesiastical affairs as connected with this people during the many centuries of their existence, but confine myself to a consideration of the origin of their distinguishing appellation, with an account of their doctrinal sentiments and religious practices, and their terrible persecutions and dispersion.
